It integrates multiple functions such as Sinochem/Jinmao brand display, urban regional future planning, business communication, and leisure; sets up Sinochem Science and Technology Museum, regional future planning sand table, VIP meeting room, and spaces of shared communication, book bar, water bar, office, etc. The design and construction of the project combine the regional characteristics of the coastal city of Qingdao, applies the concepts of green waves, sea fishing culture and green technology to the overall design, and uses a large number of log colors and plants to form a city living room with a natural temperature between the “waves”. The experience center integrates green, healthy, intelligent, scientific and technological building concepts, aiming to create an urban interactive center, sharing ecology, modernity, and technology.

Energy. This project implemented the national standard "Design Standard For Energy Efficiency of Public Buildings" (GB 50189-2015) and Shandong provincial standard (DB/J 14-036-2006). The energy consumption simulation analysis proved that 39.18% energy saving was achieved through the optimization design of building orientation, shape coefficient, and building enclosure. The project is equipped with a solar photovoltaic (PV) system, with the annual power generation accounting for 11.56% of the total energy consumption, which achieves energy conservation and carbon emission reduction.

Environment. The site of the project was originally an unused vacant space, then the concept of green waves in Qingdao coastal city was introduced into the new building design, which greatly improved the visual experience of residents. The experience center is 17.35m high, with good vision, natural lighting and ventilation. There are municipal park in the east and a ground floor building in the south. In the construction stage, according to the national green construction requirements, the project carried out measures about environmental protection and avoided the impact on residents. Meanwhile, the solid waste was classified and recycled according to municipal requirements; only units with transportation permits are qualified for the off-site transportation and ensures that the cover is tight with no scattering before the waste is reasonably treated.

Health. There is no air pollution source in the windward position of the project; the exhaust outlet of the building is not in the crowded activity area and windward side; the plants are non-toxic and harmless, exerting no impact on the outdoor environment. The magnetic field intensity around the site is less than one-fifth of the specified exposure intensity, and the transformer and outdoor units of air conditioners are set in the area far away from people's long-term stay to prevent the influence of indoor and outdoor electromagnetic radiation effectively. CFD simulation technology is used to optimize indoor air distribution and provide the best air circulation form for the building.

Comfort. The hall of the experience center adopted a glass curtain wall structure, and the light transmission area accounts for more than 70% of the entire façade. The lighting system is arranged around the building with no blind spot, therefore provided a visually comfortable environment. The indoor design temperature and wind speed are appropriate, and the room temperature and humidity can be independently controlled to ensure the thermal and humidity comfort of the personnel activity area. There is no large-scale equipment on site, no people gathering after working hours, no noise pollution; special calculation and analysis of indoor and outdoor space noise were conducted to provide users with a comfortable acoustic environment.

Owner approach of sustainability

Qingdao is located at 120°33′E 36°07′N, slightly north of the the Tropic of Cancer. According to the solar energy resources zoning in China, it belongs to the “third types” (with the annual sunshine hours of 2000-3000 h and the radiation of 502-586×104 kJ/(m³·a) and is recommended to use solar energy. The statistical data of the meteorological department shows that Qingdao has few consecutive rainy days, while the annual average sunshine hours is 2541 h, and the annual sunshine radiation intensity can reach more than 1600 kWh per square meter. Therefore, solar PV system is considered suitable from the natural conditions.

In this project, the solar PV system adopted the cadmium telluride thin-film PV glass, a thin-film solar cell based on the heterojunction of p-type CdTe and n-type CdS. The average annual power generation of the system in the first five years can be 43700 kWh, while the total energy demand of the project is only 378000 kWh, which means the renewable energy can supply 11.56% of the total energy demand. At the end of its service life, CdTe components can be recycled to reduce environmental pollution.

In this project, the refrigerant used in the outdoor unit of the multi-split air conditioner is R410A, which is a new type of environmentally friendly refrigerant that does not contain fluorine, with the ODP value of zero, and no harm to the ozone layer.
